Title: Image encoding method, image encoder and storage medium in which image encoding program is stored
Inventor: SAGATA ATSUSHI
IPC: H04N19/36
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide an image encoding method and image encoder to reduce hierarchizing loss while holding scalability when code quantity is controlled in the case of encoding a wavelet conversion coefficient. SOLUTION: An inputted moving image signal 1 is converted in a wavelet conversion part 2. The conversion coefficient is quantized at a specified quantization step in a quantization part 4 and encoded as the lowest order layer in an order from the conversion coefficient in a low band component toward the conversion coefficient in a high band component in a variable length encoding part 12. Furthermore, when the conversion coefficient is similarly quantized and encoded as a second layer at a quantization step smaller than the above quantization step, the quantization coefficient after quantization is reflectively encoded as reducing a quantization error in each layer until generated code quantity becomes specified code quantity by using an inverse quantization part 16 and a quantization part 19.  In this case, the quantization steps of each layer in object frames to be encoded are decided with a quantization step calculating part 7 by the generated code quantity of the past frame for each layer calculated in a layer code quantity calculating part 15 and the quantization steps.

Filed: 1990-01-10
Abstract: PURPOSE:To detect a splice in good response highly accurately by providing a guide shaft, a guiding contact part, a detecting shaft, a detecting contact part, a shaft linking mechanism, a detecting part and the like. CONSTITUTION:At first, a strip-shaped continuous body is moved. When a splice passes a detecting roller 20 which is a detecting contact part, the displacement of the roller 20 is converted into the turning angle displacement of a detecting shaft 18 through detecting arms 14 and 15. Therefore, the turning angle displacement is generated between the shaft 18 and a guide shaft 16. The displacement is detected with a detecting part comprising a detecting coil 42 and the like, and the presence or absence of the joint is detected. When the joint of the strip-shaped continuous body passes a guide roller 22 which is a guide contact part, the displacement of the roller 22 is converted into the angular displacement with a guide arm 26, and the turning angle displacement of the shaft 16 is obtained. The displacement is transferred to the shaft 18 through a shaft linking mechanism comprising a pin 74, a notch 76 and the like. The shaft 18 is turned in the same direction by the same angle. Therefore, the detecting part does not detect the relative turning-angle displacements of the shafts 16 and 18.

IPC: H02K11/00
Filed: 1994-01-18
Abstract: PURPOSE:To improve the precision of the detection of an overload by a method wherein the length of an amplification arm is larger than the length of a detection arm. CONSTITUTION:If a foreign substance is caught by a guide vane and stick is produced on a ball screw shaft 14 during the opening rate adjustment control, a thrust applied to a ball nut 13 as a load exceeds an allowable value. A spring 23 is bent and a spring receptacle 24b is shifted horizontally in a direction corresponding to the opening or closing control direction of a guide vane and the lower end of a detection arm 25a is also shifted horizontally. Thefefore, as the detection arm 25a is turned with a rotary arm 26g as the shaft of rotation, an amplification arm 26d is turned in the same way and the right end of the amplification arm 26d is moved along a circular arc upward or downward corresponding to the opening or closing control direction of the guide vane. As the rotation angles of the detection arm 25a and the amplification arm 26d are the same, the vertical movement distance of the right end of the amplification arm 26d is proportional to the lengths of both the arms. As a result, if the lengths of both the arms are predetermined properly, the precision of the detection of an overload can be improved.
